DHTML Trouble please help

Hi all, I am no DHTML expert and don't even know the language also didn't know where to post this. But after today I am going to learn. I downloaded a tetris game from Dynamic Drive: http://www.dynamicdrive.com/dynamicindex12/tetris/index.htm Have a look. I would add it here but it's too long. I want to add the high score to a users data in the database. Would one of you DHTML and PHP Gurues (SP) please point out what section of the code I would use to get the high score. I would like to (I can do this part if someone would show what I use from the DHTML) echo or print the score to the bottom of the browser window and then have that added to the db. TIA GC
